Google has quietly updated the LTE Nexus 7 (2013) model to Android 4.3.1, without revealing any details about what the update contains.

This isn’t the first time Google updates the software of its Nexus 7 tablets, but it’s the first time the company released a different Android version for these devices. The update probably contains fixes and improvements and we wouldn’t expect it to offer any new features.

On the same note, we’ll add that the Android 4.3.1 update is only available for the Nexus 7, and there are several firmware versions available for the JLS36I update including JSR78D, JSS15J and JLS36C.

From the looks of it, the update is already available as an over the air (OTA) download in many markets, so LTE Nexus 7 (2013) users may already have access to it. The update itself measures just 9.42MB.

Have you installed it yet? Did you notice anything different?
